Updated Canon 5D Mark II and 5D Mark III Anti-Twist Plate HDMI Protector

Ray T writes in and shares this updated version of the Canon 5D Mark II anti-twist plate [Thanks Ray]. This time, the new plate supports pin location for both the Canon 5D Mark II and even Canon's latest 5D Mark III. Anti-twist plates are important for those who don't want their cameras to shift when using items such as a Follow Focus system. The little pins fit into the alignment hole under the camera body. The plate then offers multiple threaded holes to secure your QR plates with two bolts (instead of one).

This Anti-Twist Plate now works as an HDMI cable protector with a 6 cable pinch that attaches to the side of the baseplate. If you haven't dealt with HDMI cables much, they consistently come loose of get yanked out of the camera body. At times, this cable can even cause some damage to the camera's internal HDMI port (an expensive fix). HDMI locks prevent cable shifting once it's connected to the cameras HDMI input. A cable lock like this will also save you from having to buy new HDMI cables from the constant damage.

From what I can tell, if you don't use the alignment pins, this baseplate might mount to other cameras as an HDMI lock. It also brags about how it can connect up to 6 cables at a time unlike other cable lock solutions. 6 simultaneous cable locks appears to be overkill because I doubt you'll be connecting your USB/AV port at the same time you connect your HDMI port, and also have a PC sync cord for flash photography. At most I think three locks would have been suffice - a shutter cable (5D3 starts video now), Microphone cable, and HDMI.

It is what it is, and though it will run you just under $50 bucks, it's priced cheaper than some other HDMI lock solutions and still doubles as a solid anti-twist plate. Check out the updated HDMI protector / Anti-Twist Plate over at CoolLCD (Click Here).

  1. So it's a year later and SmallHD still has not come out with this for the 7D or 5Dmk3. Really lame. There are very few HDMI lock solutions on the market. A few are $50 and a few are $150 (too much). Though I am looking for an HDMI lock that is also anti-twist.

    CoolLCD is out of this lock featured. I wrote them and they are working on a new one that only locks the HDMI port, but no ETA on release.

  2. The SmallHD solution is great but doesn't work with the 7D...they don't have an ETA on the 7D version but they are working on it.

    While 6 holes for cord protection is overkill for the cameras ports, it could come in handy to secure other cables. A few weeks ago I was shooting with a wired mic to a hot shoe mounted H4N recorder. I didn't have any issues but locking the XLR cable on it's way up past the camera would have been good insurance.

    Anyone know of a HDMI port protector solution for Canon 60D??? I really, really need one bad!

    lol I just made my own anti-twist plate for my 7D since I wasn't happy with the solutions already out there. This one looks like its compatible with the 7D because there's 3 separate alignment screws you can choose from. The main problem with other anti twist plates is there's one screw hole in the bottom, so even though the plate is secure on the camera it isn't on the QR plate. other solutions use proprietary QR systems like arca swiss. This should work no matter what your using. I like the fact that you can remove the cable lock when you don't need it.

    @Altamiradora - When using the SmallHD HDMI lock on the camera body, it doesn't pack up well, but it works great. It's a little tricky getting it on and off quickly. Here's a video with more information on the SmallHD for those who haven't seen it. https://oliviatech.com/canon-5d-mkii-port-protector-from-smallhd.

    Also, it doesn't work on the 5D Mark III at the moment. Hopefully they will have another version soon.

    Derek is right ! The SmallHD version is far better. Plus, I don't really like a gizmo that squeezes or pinch the cable itself.

    On the long run, this will damage the cable. There should have been a plate like a vise with rubber to gently press on the cables.

    I like SmallHD's version better, for mini hdmi protection. It doesn't stick out as far as this one appears to.

  8. SmallHD makes a super HDMI plate for the Canon 5DII which doesn't use the 1/4-20 tripod socket. It's the same price and works like a charm (although it won't hold in a mic cord, USB, AV or shutter release cord. I've never had a problem with those coming loose, and haven't used them at the same time as HDMI). I should mention that you can't use the camera strap lug when using the SmallHD product, because that's one of the things which holds it snugly in place. https://www.smallhd.com/canon-5d-mkii-port-protector

    This is actually exactly what I needed when I had an external monitor... HDMI cable kept bending and eventually stopped working altogether.

    @Murad - Remove the pins for anti-twist plate, and it should mount up as a cable lock. Maybe you locate your alignment hole and drill a new one.
